Good morning. This is my first post here looking for some guidance on building a certain type of test environment. I will try to concise it as much as possible.
VPP in a Ubuntu 18.04 VM 1. Configure VPP with either "dpdk" vhost mode or native VPP mode. Does not really matter for my testbed. 2. Start a container running "testpmd" in "txonly" mode. I basically use this to send packets to VPP bridge. 3. Start a container running a dpdk application that just picks up packet from rte_eth_rx_burst() and dumps it in the log. 4. Both containers use "virtio-user" as "vdev" to connect to VPP's "vhost" sockets. 5. Both interfaces are placed on a single bridge. Case-1: Using DPDK vhost * I am not seeing any packets sent by "testpmd" on this bridge. * I have set "pcap trace rx intfc VHostEthernet1, think rx on this would be tx on "testpmd". * I am not observing any packet indication. Case-2: Using VPP native vhost * Enable pcap trace on VirtualEthernet0/0/1 * Start testpmd to send packets. * Packet indication is received on container-2. * But all frames are NULL ( i.e contents are all zero ). But the length indicates some data.
